Specification of Letters Patent.

Patented Aug. 11, 1908.

Application filed July 16, 1907. Serial No. 384,051.

To all whom it may concern:

Be it known that I, AXnL B. KASPARSON, of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Device for Attachment to Card- Clothing, of which the following is a specification.

My invention relates to card clothing and especially to stiffening and protecting the ends of the clothing when in place on the flats.

My object is to provide. an end stifiener or protector which can not only be readily put in place but which will be certain to remain in place without deleterious eflect on the clothing; and my invention is a device, preferably of metal, which covers the end of the clothing and has means to positively engage that end.

A feature of my invention consists in making my device with a channel which covers the end of the clothing and in which the end is clamped.

In the drawings Figure l is an end view of a flat with the card clothing and my device in place; Fig. 2 is a side view of the same but partly in section; Fig. 3 is a plan of the clothing with my device in lace; Fig. 4 is a perspective of my device Tig. 5 is another view of my device; and Fig. 6 is an enlarged sectional view.

Card clothing A comprising the usual cloth foundation a, and teeth a is attached to flat B by side fasteners C C. These fasteners cover the side edges of the card clothing but leave the ends to be otherwisestiifened and protected. It is extremely important to have end coverings to prevent the unraveling of the ends of the clothing for two reasons, namely, to prevent the unraveling from weakening the clothing itself and so loosening and weakening the foundation for the teeth, and also to prevent the unraveled ends of the clothing from interfering with the operation of the carding machine by getting caught in other parts of the machine. It is also of great importance that the clothing be stiffened so that it will not tend to pull out from the side clips.

The end clips heretofore used have acted with some efliciency as mere protectors but they have either been so imperfectly attached to the clothing as to be readily shaken off, or they have been so securely hooked to the body of the clothing that they Work into and gradually tear it open and seriously weaken it.

My end clip D comprises lip cl parallel with the wire teeth, portions d and d to engage respectively the upper and lower surfaces of the clothing, portion (1 covering the end of the clothing and fingers d d to aid in holding the clip in position. Portion d has burs or spikes (Z d to firmly engage the clothing while portion d has burs d (1 for the same purpose. These burs are at a distance edgewise from portion d and they act with portion 01 to clamp the edge of the clothing which is held as in a vise, and which therefore cannot unravel. I prefer to have the upper and lower burs in staggered relation as shown, as in such case I get a more eflicient clamping function. While these burs most securely hold the device in place they have no tendency to tear or weaken the clothing at any part which forms the foundation or base for the wire teeth.

I refer to have the portions d and d whic form a channel for the clothing pinched together or clenched as indicated in Fig. 6, as this gives an additional clamping function supplementing the clamping function above described, and aiding the action of the spikes d d and d d. 1

Among the advantages of my device it may be noted that it is held firmly in place Without acting in any way harmfully upon the clothing and at the same time it prevents unraveling and therefore removes all danger of unraveled ends interfering with the operation of the machine. Furthermore, it is a very important advantage to have the device positively engage the endof the clothing as this enhances the stiffening function in addition to insuring a positive engagement at the desired art of the clothing.

lVhat I cl aim is:

1. As a new article of manufacture a device for attachment to card clothing com prising two parallel walls to engage the top and bottom surfaces of the end edge of the clothing and a perpendicular wall to extend along the end edge of the clothing, the whole forming a channel which is slip ed on to the edge of the clothing;and inwardly projecting spikes on one of said parallel walls forced into the clothing after the channel has been slipped upon the edge of the clothing.

2. As a new article of manufacture a deslipped upon the edge of the clothing, the 10 tWo parallel Walls being clenched together so as to grip the clothing directly between them While the spikes positively engage the cloth- AXEL B. KASPARSON. Witnesses:
